refactor(open-sse): remove reverse coupling open-sse -> src (E2)

Move clineAuth into open-sse/shared (src re-exports back). Add standalone
open-sse/shared/machineId for codex session hashing (no @/lib/dataDir).
sttCore receives sttConfig via param instead of importing AI_PROVIDERS.
No behavior change; gate: no regression (26 known-fails unchanged).
